Kua tāruatia ki te papatopenga
x+4=3\sqrt{2} x+4=-3\sqrt{2}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x+4-4=3\sqrt{2}-4 x+4-4=-3\sqrt{2}-4
Me tango 4 mai i ngā taha e rua o te whārite.
x=3\sqrt{2}-4 x=-3\sqrt{2}-4
Mā te tango i te 4 i a ia ake anō ka toe ko te 0.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
